1. A second order passive lowpass filter as shown below is designed with R=1202, L=16mH, and C=0.05μF. This is Problem 4.1 from the softcover text. A) Derive the transfer function. B) Find the poles and zeros of the function. C) Calculate @o and Q. d) Redesign the circuit to raise its quality factor to 12 without changing @o. Show the frequency response of the original and redesigned circuits in MultSim and paste the plots into your submission. R C' 2. The biquad below is to be used to design a bandpass filter with center frequency fo=3.2kHz, Q=7.5. and midband gain 24dB. A) What is the filter's 3dB bandwidth? B) Simulate the filter in MultiSim and using practical component values and LM741 opamps. Paste the plots of the frequency response magnitude and phase into your submission. C) Also show the frequency response magnitude and phase at the lowpass output. This is a modification of Problem 4.5 from the softcover text. R3 R₂ C₂ R₁ w -K R$
